Abstract (en)
[origin: EP0537803A2] In television cameras, there is a risk that the image will wobble due to an unwanted movement of the housing. According to the invention, a television camera is provided with a target onto which a desired image field is projected by means of optics and which is scanned along a raster in order to generate the video signal, the target being larger than the field of view and an actuating variable being obtained from a movement of the camera, which variable allows the starting point of the scanning raster on the target to be displaced. The actuating variable is obtained in a comparator or correlator which compares the image signals of successive frames or parts thereof and, in the case of a signal difference above a threshold value, generates the threshold variable. <IMAGE>
